The biggest concert of the year has sold out, but don't despair. The "12-12-12" benefit to help the victims of Hurricane Sandy tonight at Madison Square Garden will be streamed and broadcast on too many outlets to count, making it the most widely distributed live music event ever, according to its organizers.

Close to two billion people in more than 190 countries worldwide will have the opportunity to watch the 12-12-12 concert, organizers said. The concert, which is presented by Chase bank, will be available to all 114 million U.S. TV households and more than 400 million TV homes internationally in North and South America, Europe, Africa, Asia and Australia.

Online live streams for the 12-12-12 concert will be available beginning at 7:30 p.m. EST on YouTube, AOL, Yahoo, Hulu, and numerous others, which, when combined reach more than 1.4 billion monthly unique users worldwide.

Clear Channel Media and Entertainment will air the concert live on its radio stations across the U.S. and video stream it on its digital radio service iHeartRadio, reaching another 239 million monthly listeners and more than 48 million monthly digital unique users, according to the Hollywood Reporter.

"We are proud to be able to say that this concert is already setting records by securing near total distribution around the world," event producers James Dolan, CEO of Cablevision Systems and chairman of Madison Square Garden, John Sykes, president of Clear Channel Entertainment Enterprises, and Harvey Weinstein said in a joint statement.

"The massive distribution means that the concert will be available to almost anyone on the planet with a television, a radio, a smartphone, tablet, computer or Internet-connected device."

Proceeds from the concert will go to the Robin Hood Foundation, a New York City group, the Wall Street Journal reported.

Paul McCartney will reportedly "reunite" the defunct iconic 90s grunge rock band Nirvana for the concert, filling in for deceased singer/songwriter Kurt Cobain.

Nirvana drummer Dave Ghrol apparently asked McCartnet to join him and bassist Krist Novoselic to play at the 12-12-12 concert, reported The Sun.

"I didn't really know who they were," the 70-year-old Beatles legend told The Sun. "They are saying how good it is to be back together. I said, 'Whoa? You guys haven't played together for all that time? And somebody whispered to me, 'That's Nirvana. You're Kurt.' I couldn't believe it."

According to The Sun, McCartney, Grohl and Novoselic have been rehearsing in secret to get ready for the benefit. McCartney also performed with Grohl at the Grammys earlier this year.
